A 1.2 kg, five-month-old, female domestic short-hair cat was referred to Seoul National University Veterinary Medical Teaching Hospital with a history of vomiting immediatley after eating. Clinical signs were depression, anorexia, severe dehydration and vomiting since weaning. According to history taking, physical examination, complete blood count, serum chemical profile and contrast radiographic study, it was diagnosed as congenital sliding esophageal hiatal hernia. Diaphragmatic plication, esophagopexy and left-sided belt-loop gastropexy were performed. Ranitidine (2 mg/kg, IV, q12h) and sucralfate suspension (20 mg/kg, PO, q6h) were administered with low-fat liquified diet to treat reflux esophagitis. Clinical signs related to esophageal hiatal hernia disappeared immediately after surgical treatment and did not recur for 4 months.

A 900 g seven-month-old female scarlet macaw was referred to Seoul National University Veterinary Medical Teaching Hospital with history of rupture of a crop. Formula leaking from the crop fistula onto the chest feathers was found. According to history taking, and physical examination, the avian was diagnosed as the burns on both right and left surface of the crop. After anesthetizing it with ketamine(50 mg/kg, IV), necrotic tissue of the skin and crop was excised. The crop wall and skin were closed in layer by layer. Metronidazole (50 mg/kg, sid, PO) was administered for 5 days postoperatively. The meal was given frequently with smaller amount. There has not been any digestive problem for 2 months after treatment.

A 5 kg, seven-month-old, female Pekingese dog was presented to Seoul National University Veterinary Medical Teaching Hospital with the history of anorexia and exercise intolerance. Muffled cardiac sound and mild abdominal pain were detected in the physical examination. In positive contrast peritoneography, contrast medium was observed in enlarged pericardial sac through the diaphragm. According to the history taking, physical examination and contrast radiographic study, the dog was diagnaosed congenital peritoneopericardial diaphragmatic hernia. Following midline celiotomy, herniated falciform ligament and greater omentum were repositioned to abdrminal cavity. The diaphragmatic defect was closed with absorbable suture. Clinical signs related to peritoneopericardial hernia disappeared immediately after surgical treatment. There had been no evidence of recurrence of the peritoneopericardial hernia for 1 year.

Japanese mathematics, namely Wasan, was well-developed before the Meiji period. Takebe Katahiro (1664-1739) and Nakane Genkei (1662-1733), among a great number of mathematicians in Wasan, maybe the most famous ones. Taking Takebe and Nakane's indefinite problems as examples, the similarities and differences are made between Wasan and Chinese mathematics. According to investigating the sources and attitudes to these problems which both Japanese and Chinese mathematicians dealt with, the paper tries to show how and why Japanese mathematicians accepted Chinese tradition and beyond. As a typical sample of the succession of Chinese tradition, Wasan will help people to understand the real meaning of Chinese tradition deeper.

Modern wind turbines have been mainly erected in region where earthquake are rare or normally weak, especially Korea was thought as safety zone from earthquake. But recently, the earthquake occurs more and more frequently. So, the wind turbine design is required the structural and functional stability under the earthquake. The earthquake can influence normal operation, even if a weak earthquake. There are two ways to review the design under earthquake using Computer Applied Engineering (CAE). One is the Response Spectrum Analysis (RSA) the other is Time History Analysis (THA). In this research, dynamic response on time is obtained under the earthquake by taking into account ground accelerogram consistent with the relevant standards applied to the turbine foundation.

The city of Dalian has been developed under varied geo-political situation since the later part of nineteenth century up to now where a considerable mutation is taking place. In this study we tried to trace the historical evolution process of Dalien as second important port of China playing the role as center of North-Eastern Region in the field of Industry, foreign exchange, finance and tourist industry. The result reveals possibility of the city to excelerate its development under present circumstances toward the opened system of economical policy.

By taking the Runyang Highway Bridge over the Yangtze River with 1490 m main span as example, structural response of the bridge under the horizontal and vertical seismic excitations is investigated by the response spectrum and time-history analysis of MIDAS/Civil software respectively, the seismic behavior and the influence of structural nonlinearity on the seismic response of the bridge are revealed. Considering the aspect of seismic performance, the suitability of employing the suspension bridge in super long-span bridges is investigated as compared to the cable-stayed bridge and cable-stayed-suspension hybrid bridge with the similar main span. Furthermore, the effects of structural parameters including the span arrangement, the cable sag to span ratio, the side to main span ratio, the girder height, the central buckle and the girder support system etc on the seismic performance of the bridge are investigated by the seismic response spectrum analysis, and the favorable earthquake-resistant structural system of suspension bridges is also discussed.

In this study, we took a look at Joseon's Korean-Japanese Medical Science Cultural Exchange Context through SangHanUiDam(桑韓醫談). SangHanUiDam(桑韓醫談)'s contents mainly include patient treatment and consultations on medical theory, starting from distinguishing medicine. Like the views many scholars that studied Joseon Diplomatic Missionary hold, even in SangHanUiDam(桑韓醫談)'s Medical Science Cultural Exchange, Japan shows great enthusiasm in taking in Joseon's medical culture.

A high embankment is generally constructed by dividing into several sub-embankments. Unlike any soil embankment, a rock embankment is constructed by means of dynamic compaction. Such a sub-embankment and dynamic compaction may induce an increase of pressure at the lower part of embankment and cause a different behavior of ground from initial status. In this study, settlement of a high rock embankment is estimated using a hyperbolic model taking into construction history. The results from prediction are compared with those obtained from field measurements and large plate loading tests.

Now a days, the fabrication and election skills have improved in Korea. Due to taking the vertical clearance and a point of beauty, the election of the suspension and the cable-stayed bridges whose span length can be lengthened have been increased. Accordingly, there are link areas between the bridges by cables and other bridges. These dynamic behaviors are different from others. When the vehicles and trains run on the link area, the member force and the fatigue behavior which are occurred to the structure have different values depend on the velocity. On this paper, we analyze the bridge behavior by means of the tine history analysis depend on to velocity, the number of vehicles, single and double way.
